MORRIS ENGINEERING & ASSOCIATES, INC. <br /> CONSULTING ENGINEERS <br /> Secondary Containment Checklist <br /> Secondary Containment Name: ContainmentA(Al +A2+A3) <br /> Approximate Dimensions: See attached secondary containment plan <br /> Volume of Secondary Containment: 6461 gallons(See attached calculations) <br /> Volume of Largest Tank: 5800 gallons <br /> Does the Secondary Containment Have Yes <br /> Sufficient Capacity: <br /> Typoe—of Secondary Containment: Lined Concrete Berm <br /> Material of Construction: Epoxy Coated Concrete <br /> Is the Containment Designed to Yes <br /> Prevent Migration of Wastes to the <br /> Soil,Ground Water,or other Areas <br /> Outside of the Containment: <br /> FIs the Containment Located Indoors or Yes <br /> is Precipitation Run-on Prevented: <br /> Type of Spill Monitoring System: Visual observation from facility staff members. No standing water <br /> was noticed during our observation. <br /> Description of Structural Damage: The concrete berm appeared to be in good condition, but there <br /> were several structural cracks that should be repaired to ensure <br /> the tightness of the containment. The underground sump also had <br /> several structural cracks in the concrete walls that should be <br /> repaired. Additionally, the epoxy coating appeared to be worn in <br /> the sump and the bermed area. It is our recommendation that the <br /> epoxy coating be reapplied to ensure the secondary containment is <br /> behaving as designed. An epoxy specialist should be consulted <br /> prior to applying the coating to confirm the type of epoxy that <br /> should be applied. It is also recommended that a leak test be <br /> performed on the underground sump after the repairs have been <br /> made to ensure its watertightness. These repairs need to be made <br /> prior to using a Zinc-Phosphate solution, but do not need to be <br /> made at this time. <br /> 1300 INDUSTRIAL ROAD, SUITE 14, SAN CARLOS,CA 94070, (650)595-2973 FAX(650)595-2980 <br /> Email: lee@moniseng.com <br />
